Araldite = epoxy no? That how-to ages ago was with aradite and wet 'n' dry. Probably worth protecting the unscratched area with masking tape or similar.

I sold some scratched forks with my old frame to a bloke who worked in a big marine engineering place. He repairs massive hydraulic rams with solder apparently, he reckoned if it was good enough for industrial rams, it would work with fork stantions, probably easier to rub down too.
